Solutions
Expert Solution
Solution:
Given: there are 9 different sandwiches, six different cookies and and four different drinks available.
We have to find number of ways of different Combos that are possible.
A Combo which consists of a choice of sandwich, a cookie and a drink.
So to select a combo, we need to select one from each.
Thus we need to use multiplication principle of counting.
If there L ways of first procedure , M ways of second procedure and N ways of third procedure
then total number of ways of performing all three procedures = L * M * N
Thus
Total number of ways of different Combos = 9 * 6 * 4
Total number of ways of different Combos = 216

A diner has no competition when it comes to its famous Reuben sandwich combo plate, for which the graph shows the diner's demand (D), marginal cost (MC), and marginal revenue (MR) curves.
A diner has no competition when it comes to its famous Reuben sandwich combo plate, for which the graph shows the diner's demand (D), marginal cost (MC), and marginal revenue (MR) curves. The price of $20 is based on the MR MC rule for profit maximization. The rectangular region shown represents the net revenue from sales of the sandwich (total revenue from Reuben combo sales minus total variable costs associated with Reuben combo sales) Now, suppose the diner decides to raise...
